PLATE-GLASS SETTING.

SPECIFICATION forming part of Letters Patent No. 593,110, dated November 2, 1897.

Application filed March 25, 1897. Serial No. 629,232. (No model.)

To @ZZ whom, t may concern:

Be it known that we, .lov Lovn and JOHN I). LOVE, of Aurora, in the county of Kane, and in the State of Illinois, have invented certain new and useful Improvements in Plate- Glass Settings; and we do hereby dec-lare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure l is a front elevation of a portion of a building-front in which the glass is set according to our invention. Fig. 2 is a hori- Fig. 3 is a det-ail view in section on the line a: Fig.V l, showing the construction by which the glass is secured at its bottom edge; and Fig. 4 is a section on the line y y, Fig. l., showing the construction by which the top edge of the glass is held.

Letters of like name and kind referto like parts in each of the figures.

The object of our invention is to provide a construction of frame or sash forholding large plate-glass for store-fronts that will enable the glass to be set from the outside of the building and which will diminish materially liability to breakage from the edects on the glass and frame of changes in temperature.

To these ends said invention consists in the frame or sash constructed substantially as hereinafter specified.

In the drawings our improvements are shown as applied to a store-front which is divided into several panels which are glazed with sheets of plateglass,the frame or sash for each sheet of glass being formed by parallel horizontal and vertical metal bars. In the outer side of each of said bars A and A, on its inner edge, is provided a groove or rabbet a for the reception of the edge of the glass, and the latter is confined therein by a bar B, that is fastened by bolts or screws to each of the bars A on the outside thereof, so as to overlap the edge of the glass on the outside.

The bars A and A, which are preferably of steel, are T or angle bars, according to their situation, one web or flange being the means whereby it is secured to the building structure, and the groove or rabbet a being provided in the other. Said groove or rabbet may consist of a cavity in the bar, but preferably it is produced by bolting or screwing required capacity for yielding.

to the bar A a thin bar O, less in width than the bar A by an amount sufficient to provide the required space to form the rabbet.

In the groove or rabbet d of the bottom bar A there is placed a strip of lead D, on which the lower edge of the plate of glass rests, which constitutes a sufficiently-yielding cushion or support for the glass to prevent its breakage from its own expansion and the contraction of the metal frame,caused by changes in temperature. Lead is employed because of its durability and because it possesses all At the two side and top edges of the glass packings E, of leather strips, are used for a like purpose.

The joints, both inside and outside,between the glass and the frame are sealed by a composition of litharge and glycerin.

It will be observed that the construction of our frame with the glass-securing strips on the outside of the building is such that the glass is set or placed in the frame from the outside. Heretofore it has been the invariable practice in glazing large windows with plate-glass to set the glass frornwithin the building. This, besides requiring such handling of the glass as to expose it to great danger of breakage, made its setting inconvenient and awkward, and in the erection of new buildings required its being set before the building was otherwise complete, thus eX- posing it to the danger of breakage by the careless handling by workmen of building material.

lVith our construction the handling of the glass is simplified, it being possible to set the large plates by backing the dray or wagon hauling the same into such position in front of the window as to enable the glass to be unloaded from the same directly into place, and the setting of the glass can be delayed until the building is otherwise complete.

The bars A and A, forming the frame, are of course materially strengthened by the bolting or screwing thereto of the bars B and O.

Having thus described our invention, what we claim isl. A metal frame for plate-glass composed of bars to which other bars of less width are fastened to form rabbets for thev reception of the edges of the glass, glass-securing bars IOO the glass, substantially as and for the purpose speied- In testimony that We claim the foregoing We have hereunto set our hands this 12th day I 5 of March, 1897.

JOY LOVE. JOHN P. LOVE.
